An unanticipated but severe shortage in iodinated contrast media (ICM) is currently affecting imaging practices across the globe and is expected to persist through at least the end of June 2022. This supply shock may lead health care systems to experience an acute imaging crisis, given that many affected facilities have contrast agent supplies that are anticipated to last only a week or two under normal operating conditions. To maximize the opportunity to continue to provide optimal care for patients with emergent or life-threatening imaging indications and thereby minimize the overall impact on patient care, practice leaders will need to quickly assess their contrast material inventories, prioritize examination indications, and reduce their expected short-term usage of ICM. This Clinical Perspective reviews ICM conservation techniques that the Yale School of Medicine has deployed or is considering deploying, depending on the severity and length of the supply shortage.
目前，全球各地的影像检查实践都受到了碘化对比剂（ICM）意外且严重短缺的影响，预计这种情况至少会持续到 2022 年 6 月底。这种供应冲击可能会导致医疗系统面临急性影像危机，因为许多受影响的医疗机构预计在正常运营情况下，造影剂的供应仅能维持一到两周。为了最大限度地为有紧急或危及生命的影像指征的患者继续提供最佳护理，并尽量减少对患者护理的整体影响，实践领导者将需要快速评估他们的造影材料库存，优先考虑检查指征，并减少他们对 ICM 的短期预期使用。本临床观点回顾了耶鲁大学医学院已经部署或正在考虑部署的 ICM 保存技术，具体取决于供应短缺的严重程度和持续时间。
